Now press F8 once more and execution should advance to the following instruction of CALL vulnserv.00401020. What this red highlighting of values is indicating is that this particular value changed during the last operation. The EBP register will change to match that of the ESP register, and the EBP and EIP registers values will be highlighted in red.
In addition, the instruction following PUSH EBP in the top left hand pane, namely MOV EBP, ESP, should now be highlighted, and two registers, ESP and EIP have their values highlighted in red to indicate that they have changed. The F8 key is a shortcut key for the Step over operation, which allows you to advance forward one instruction, while NOT following any function calls. In the top left hand pane of the CPU view you should see the instruction PUSH EBP highlighted. If you havent already, start up OllyDbg and open vulnserver.exe.Įxecution should automatically pause at the program entry point.
You may want to run normally at one point, to go step by step through each individual instruction at another, and sometimes to have it run quickly to a particular point allowing you to take control once that point is reached.
Now right click in the top left hand pane of the CPU view and select Search for-All referenced text strings. Ollydbg Patch Plugin By fraphardventa1980 Follow | Public
